7th World Conference on Marine Biodiversity (WCMB 2026)
The 7th World Conference on Marine Biodiversity (WCMB 2026) — themed “The marine biodiversity insights we need, for the ocean we want” — is organized by the Flanders Marine Institute (VLIZ) and endorsed as a UN Ocean Decade event. Taking place a little over halfway through the Decade, it is an opportunity to take stock of ongoing actions and evaluate what remains to be tackled.
On the opening day, Tuesday, 17 November , two sessions will showcase the work of the Marine Biodiversity Observation Network (MBON) (session 7.1) and the Marine Life 2030 Ocean Decade programme (session 1.1), two initiatives central to strengthening coordinated biodiversity observation worldwide.
